The aircraft bears the company designation XA41, but is marketed under the name Sbach 300, although use of this name was later abandoned.
The Sbach 300 is an all-composite design, predominantly constructed of carbon fibre. It features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration. The aircraft's 7.51NaN1 span wing has an area of 11.25m2 and mounts full-span ailerons with spades to lighten control forces, which give a roll rate of 450° per second. The standard engine employed is the 3150NaN0 Lycoming IO-580 four-stroke powerplant. The aircraft has an empty weight of 570kg (1,260lb) and a gross weight of 850kg (1,870lb) for aerobatics and a gross weight of 999kg (2,202lb) for non-aerobatic flight.[2]
The 300 was later developed into a two-seat version, the XtremeAir Sbach 342, which was introduced in 2007.
The Sbach 300 was flown to a German national aerobatic championship in the unlimited class. Seven XA41s were completed by XtremeAir by 2020, with an additional example completed from a kit. Another XA41, powered by a 360hp Vedeneyev M14P was completed with the name Angry Fish.
